. To all whom it may concern.

Be i-t-l'rnown that I, VI-oToR L. Cnoss, a "citizen ofthe United States, residing at Detroit.

in the county of Wayne and State of Michigan, have-invented certain new anduseiul Imp re-vement's in Micrometer Height Gauges, of which the following is a specification.

This invention relates to new and useful improvements in measuring devices, and

mere particularly to gauges whereby a deviceof this character is provided with Die-ans for accurately and minutely adjusting the niovable jaw of the gauge so as to expedite accurate measurement.

Another object'of the invention is to provide a gauge of this character, which is provided with the usual type of movable jaw, which is adjustable toward and from a stationary base, and, said jaw is provided with means for adjusting the same-slightly after itl has been fixed at'certain predeter- "mined positions, said meansinclud'ing'aisupfplernental' gauge so that thelaccurate Ineasurein'eiit to 't-hefraction of anin'ch may be easily determined v A further object of the invention is to provide a height measuring gaugeoi'this character, with a "micrometer attachment,

' that is operatively associated therewith and g to constitute a hub for embracing therod 6,

w en; permits a frictionaladjustment be- "tween-a predetermined scale of thega-u'ge and which is provided with a supplemental "g'a'uge" on, the micrometer.

proved device.

il'l further object oi the inventi'o{n isv provide a; device or this character which easily and simply constructed, inexpensiv to manufacture, and one wh ch w1l=l be very efficient in operation.

The numeral 1 designates the stationary base ofmy new and improved gauge, which "is o-f 'the usual point intermediate its ends, a stationary guide rod 2, is the usual type of movable jaw 3, proyided with a projecting jaw per -'t1on-4, Wh1ch is movable toward and rfreni guide rod 2; Slidably mounted upon {the the stationary base 1, in la r-manner to he hereinafter more. fully described. The.

75 V I arranged in staggered. relationtoeach other I connected by a micrometer attachment 13, with the base i, which attachment is carried by a stationary sleeve 16 rising from the inner end of the base for the purpose I securing the sleeve 16 in position, the'same has its lower end threaded, as at through a complementally threaded opening'li formed immediatel inward of the inner end 5 at the base 1, after a loclrnut l'? has been threaded upwardly of the lower end of the sleeve 16, which lock nut will abut'the upper face of. the base 1, when properly'positioned, and the lower end of the sleeve 16 will termlnatein the plane of the lower face of the base-1, which is formed to provide a countersink concentric to the sleeve 16, whereby to admit of the threading thereon of a second lock nut 17, which, when tightened inwardly of the countersink acts in conjunction with the upper lock nut 17 to retain the sleeve 16 rigidly in position. v

Mounted within the sleeve 16 is a screw 18 which is in engagement with screw threads 19 internally of the sleeve 16 carried by the base 1. The headedportion of the screw 18 projects above the upper edge of the sleeve 16, and surrounding the upper portion of said sleeve and the headed portion 20 is a micrometer barrelQl which has its outer surface roughened, while the lower edge .is pro vided with a scale ZQ-thereon to coact with i} 7 a suitable indicator mark uponthe base adjacent to the lower edge of the barrel 21 for permitting accurateminute adjustment of the jaw 3 in the use of the implement. r

'Ihe h'eadQO of the screw 18, is securely connected with the barrel 21, by a locking pin'22, which projects therethrough, and

hence upon rotation of the barrel, the screw,

will be correspondingly rotated. Swivelled within the upper end of the barrel is the head portion'of' a screw 2a, which has its shank projecting upwardly fromthebarrel,

and its extremity disposed in a recess 25in the lowerend of the rod. This extremity is securely held within the recess in therod by a cross pin 26. This connection forms a swivel between the barrel and the rod 6, and hence the rod'6 is movable longitudinally toward and from the stationary base 1.-

Lock nutsQ/Y are provided on the screw 2i to take up lost motion in the swivel. These look nuts 17 rest closely on the upper end of the sleeve 13, with the lower lock nut.

contacting the sleeve for suchpurpose.

In operation, thefgauge is adjusted to the article, in the usual manner by sliding the the nearest practical position corresponding 1 I to the dimension ofthe article to be-meas- .the aligning openings in" the extension 8- movable jaw on the guide rod 2, and the extension 8thereof being likewise moved on the rod 6. The. movable jaw is looked in ured, by inserting the locking pin 11 through and rod 6, Which are nearest to the desired For 7 adjustment. This will lock the jawjat an easily determined number of inches from the stationary jaw. Then the movable jaw'is locked in this first position, the fractional inch adjustment is obtainedby rotating the micrometer, that is the barrel 21 which will adjust the jaw by moving the rod 6'longituwith the object and bymeans of the scale 22 on the lower edge of the, barrel 21', the fracdinally. This willbring the aw in contact '75 V 1 tional adjustment to a very fine degreemay"v scribed the device as embodying aspeciiic structure, I desire that it be understood that such changes may be made in said construe tlOIl as do not depart from the spirit and.
